Problems solved by technology

Due to the certain elasticity of the steel wire rope, the movement speed of the mold core is uneven during drawing, so although this method improves the accuracy of the inner hole of the barrel, it is very unstable.

Abstract

A hydraulic press based on the drawing technology of long hole features that the front and back beams are installed to the front and back ends of a rectangular bench, the supporter for fixing work-piece and several regulate three-point supporters are installed on a platform installed to the back end of bench, the locating flange for holding work-piece is installed to side back surface of said back beam, the regulate core die supporters are installed on said platform and bench, the cylinder body and its several regulate supporters are installed on front beam, and the piston rod in cylinder is pinned to a connecting rod pinned with core die.

Description

technical field [0001] The invention relates to a horizontal hydraulic press, in particular to a hydraulic press based on a long-hole drawing process. Background technique [0002] Machining long holes has always been a difficult problem, because the tool rod is too long, its rigidity will decrease, not only the machining accuracy is poor, but also the finish is not high. , and the hardness and smoothness requirements of the inner surface are also relatively high. At present, there is a drawing process method to solve the ballistic processing of the gun barrel, which has achieved better results. The inner diameter of the barrel is similar to the mold core, and the hoist and wire rope are used as power to pull the mold core through the inner diameter of the barrel, and the inner surface of the barrel is squeezed by the mold core to achieve the purpose of correcting the accuracy of the inner hole. Due to the certain elasticity of the steel wire rope, the movement speed of the...
